Rail-bound vehicle for an amusement park ride

ABSTRACT

The invention relates to a rail-bound vehicle for an amusement park ride. The vehicle has an upper part  10  with vehicle seats  12 , as well as a carriage  20  whose running wheels  22  and lateral wheels  23  run on rail-tubes, as do its lift-off rollers  24 . The upper part  10  can rotate freely around a vertical axis  16  relative to the carriage  20 . A brake disk  14′  made of a metallic material is provided on the underside of the upper part  10 . Permanent magnets  31  connected to the rail system are assigned to this brake disk  14′ . The brake disk  14 , upon passing these permanent magnets  31 , enters the latter&#39;s magnet field, with the result that the upper part  10  of the vehicle is braked and set into rotational motion due to the continued linear movement of the carriage  20.

The invention relates to a rail-bound vehicle for an amusement park ride, of the type indicated in the preamble of claim 1.

The invention is based on the amusement park ride known from DE 195 25 429 C3.

The cited ride involves vehicles which are guided on rails and which basically consist of a carriage that moves in the direction of the rails and an upper carriage or upper body which is swivel-mounted on the carriage, while the center of gravity of the upper carriage is eccentrically positioned, at a distance from the vertical axis of rotation. During travel on the track rails and while passing over curves, the upper carriage experiences a centrifugal force due its eccentric mounting, and this causes the upper carriage to execute a turning motion around its axis. To control the relatively complicated turning movement it is necessary to provide cushioning devices using viscous or frictional cushioning or employing an eddy current.

The present invention proposes a simpler solution, one which deliberately abandons the eccentric mounting of the upper carriage (which is somewhat problematic) and thus also abandons a rotating drive that utilizes centrifugal forces.

In accordance with the solution according to claim 1, there is assigned to the upper part of the vehicle a magnetic system which consists of at least one magnet and of one metallic braking element passing through the magnetic field of the magnet and preferably consisting of aluminum or brass. The magnet is firmly positioned in the area of the track, while the braking element is connected to the upper part of the vehicle. Upon locomotion of the vehicle, the magnetic system generates a decelerating impulse that works on the upper part, as based on the operating principle of an eddy-current brake, and the upper part consequently experiences an angular momentum.

To be sure, the use of a magnet to actively set the passenger-carriers of a carousel into circular motion is known from DE 205 596 A.

In this carousel, however, unlike the ride according to the invention, the circular motion of the passenger-carrier, and thus the upper part, is not derived from the linear motion of the vehicle.

As with a roller coaster, the vehicle according to the invention may be driven by gravity or by a motor.

The same effect can be achieved when, conversely, braking elements are firmly positioned in the area of the rail path and the magnet is connected to the upper part.

As proposed in claim 2, the magnetic system can either be controlled in programmed fashion as a function of the vehicle's position or can be actively controlled by a passenger seated in the vehicle. In this manner, the time and place, or the direction and speed of rotation, can be influenced.

If the magnetic system has permanent magnets, as suggested in claim 3, it is possible to realize the elucidated control system by positioning the magnet in the manner proposed in claim 5.

If, as proposed in claim 6, the magnet is an electromagnet, the control system can be realized with the current fed to its excitation coil.

In the preferred exemplary embodiment of claim 7, the braking element is positioned on the underside of the vehicle's upper part, while stationary magnets are positioned in the area of the rail track, in the path of this braking element.

Embodiments of this braking element in the form of a disk or a ring are the subject matter of claims 8 to 11.

While a circular or annular braking element provides uniform deceleration of the vehicle's upper part, a design deviating from a circular shape—e.g., as proposed in claims 9 to 11—provides a predefined orientation, e.g., in the area of slow sections of travel or in the train station. It is advantageous, therefore, if the upper part of the vehicle occupies a position—e.g., while in the station area—which permits the passenger to enter and exit the vehicle, or at least makes the process easier. This is proposed in claim 12.

The system according to the invention, as well as further details of the invention which are the subject matter of the claims, are next described in greater detail on the basis of exemplary embodiments, which are schematically depicted in the drawings. Shown in the drawings are:

FIGS. 1 and 2 show a vehicle equipped with a magnetic braking system in accordance with the invention, for travel on rail tubes 30, in an amusement park ride that is not depicted in detail, e.g., like that of a roller coaster.

The vehicle consists of an upper part 10, with passenger seats 11 and with retainer systems 12 assigned to them. These parts are positioned on a circular platform 15, which can freely rotate relative to the carriage 20, around a perpendicular axis 16, which is indicated by the segmented line in FIG. 1.

The carriage consists of a frame, which is not depicted in detail, but which can be more closely identified in FIG. 4. The frame exhibits vehicle axles 21, which run on the perpendicular, and one main beam 26. The vehicle axles 21 support wheelhouses 25, and running wheels 22 are swivel-mounted on these wheelhouses 25, as are side wheels 23 and lift-off rollers 24, which operate at the front to prevent lifting.

The running wheels 22 and side wheels 23, as well as the lift-off rollers 24, are positioned perpendicular to each other and move on the surface of the rail tubes 30. Transverse members 33 serve to stabilize the rail system.

On its underside the platform 15 of the upper part 10 exhibits a rotating seat 13, which in turn is equipped with a metal brake disk 14′ on the side facing the carriage 20. This brake disk 14′ has radially projecting segments 14′a, which are distributed over its circumference. Assigned to the brake disk 14′, with segments 14′a, is a permanent magnet 31, which is supported by a magnet holder 32 connected to one of the transverse members 33 of the rail system.

The magnetic brake system consisting of brake disk 14′ and permanent magnet 31 is next explained in greater detail on the basis of the enlarged depiction provided by FIG. 5. In this embodiment the permanent magnet 31′ has two pole shoes 31 a and 31 b, which border an air gap 31 c. The brake disk 14′, which is firmly connected to the upper part 10 of the vehicle, dips into this air gap 31 c, and an eddy current is consequently produced in the brake disk 14′ due to induction. This leads to the vehicle upper part 10 being braked, in keeping with the operating system for an eddy-current brake. Since the vehicle continues to move in the longitudinal direction, braking causes the upper part 10 of the vehicle to rotate.

A somewhat different design for the permanent magnet 31′ is shown in FIG. 6. Here the permanent magnet 31′ has only one pole shoe.

The same effect can be achieved by providing electromagnets in place of the permanent magnets. These electromagnets can be controlled by changing the coil current, as dependent on the program that is provided; or they can be interactively controlled by the passenger.

To control the magnetic system operating with permanent magnets the arrangement depicted in FIGS. 7 and 8 is proposed as exemplary. Here there is assigned to the circulating brake disk 14′ a permanent magnet 31″, which swivels around the axis 34, so that it can be brought from the position shown in FIG. 7 to that shown in FIG. 8. The magnetic system is thus controlled in a purely mechanical manner.

Various design possibilities for the brake disk or brake ring are depicted in FIG. 9 to 12. The simplest form for a brake ring 14 is depicted in FIG. 9. When this brake ring 14 enters the magnetic field of the permanent magnet (not depicted) the result is a uniform deceleration.

FIG. 10 shows the exemplary embodiment of a brake disk 14′ with radially projecting segments 14′a distributed over the circumference; here brake deceleration is only achieved when the segments 14′a enter the magnetic field of the permanent magnet. This allows the realization of preferred orientations for the upper part of the vehicle.

For continuous modification of the braking effect, a comparable effect can be achieved with a brake disk 14″ that is positioned eccentric to the rotating axis 16, as is shown in FIG. 11.

In another exemplary embodiment, shown in FIG. 12, the brake disk 14′″, which is roughly oval in shape, exhibits indentations 14′″b. These indentations give the upper part 10, which rotates relative to the carriage 20, a preferred position when there is again a continuously changing effect.
